IMPROVEMENT IN FILE-HANDLES.

TO .ALL WHOM IT MAY CONCERN:

Be it known that I, ALFRED WEED, of Boston, in the county of Suffolk, and State of Massachusetts, have invented an improved File-Holding Handle; and I- do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sulcient to enable those skilled in the art to practise it.

This invention is specially designed and adapted for holding iu adjustable jaws, attached to a handle, such tiles as are constructed without a tang, and it consists in the peculiarities of the details of construction and arrangement of the metallic grasping-jaws, and the parts therewith immediately connected.

Figure 1, of the drawings, is a longitudinal section taken through the centre of the handle, the jaws, and

the file grasped thereby', while Figures 2, 3, 4, and 5, show end views of the jaws, each respectively grasping a at, a square, a triangular, and a round file.

`a'. represents an ordinary handle, into which is driven the spindle b, this being formed integral with the shoulder e and ixedjaw rZ. The loose jaw e is provided-with a screw,f, and nut, g, by means of which the loose jaw can be drawn toward the fixed jaw, and thus clamp any tile which may be inserted between the jaws. The rear end of the loosejaw abuts against the front falce of the shoulder c, and is thereby prevented'from turning on the screwf, as a pivot, which, being located near the rear of the loose jaw, gives room in front of the screw for entering the rear end of the file. In both the fixed'and loose jaws grooves are made, preferably corresponding, to each other, and ofthe right-angular form shown, said grooves being adaptechas seen in figs. 3, 4, and 5, to rmly hold any file of theforin of section shown in said figures, while dat and half round tiles are held firmly between the parallel faces of the jaws, there being at the rear end of such forms of files a notch which rits upon the screw between thejaws, and thus practically prevents lateral movement of the files.

With three of these handles, one large, one medium, and one small, a machinist may make use of u large assortment of iiles. v

To render the holding of les between thejaws of my improved handle still more certainly immovable, olie of the jaws, preferably the fixed one, may be constructed with a rib on its face, as seen at 7L, corresponding grooves being made in the dat files to be held. l

I claim a tool-holding handle, as made with jaws, arranged to have an adjustment with respect to each other, one or both of which are provided with a transverse rib or ribs, and a longitudinal groove or grooves, constructed substantially as described.
